ANSWER ASAP. Two students were given the expression shown to simplify. Use the drop-down menus to complete the statements about whether each student's answer is an equivalent expression. Then choose an expression that is equivalent.

Expression is 9-(3-6x)
Options for Sergio 9-(-3x) are: Correct or incorrect because (he should multiply before subtracting, he should subtract 9-1 first, he cannot simplify 3-6x, he correctly simplified in the parentheses first, he did not multiply 3 by -1 correctly, he distributed correctly)

Options for Leon 9+3+6x are: Correct or incorrect because (he should multiply before subtracting, he should subtract 9-1 first, he cannot simplify 3-6x, he correctly simplified in the parentheses first, he did not multiply 3 by -1 correctly, he distributed correctly)

And for the correct equivalent expressions: 9+3+6x, 9+3-6x, 9-3+6x, 9-(3x), 9-(-3x), 8(3-6x)
